Future work lies in evaluating alternative affine region detectors [1]}, refinement methods, and sampling strategies [2]} to further speed up the localization process and increase reliability. Our work provides a foundation for study of related absolute pose problems with ACs such as handling uncalibrated cameras [3]} and radial distortion [4]}. The application of ACs to these problems could greatly reduce number of correspondences needed in comparison to approaches based purely on PCs, and would broaden the applicability of the approach to localizing “in-the-wild” images for which camera calibration is not available beforehand.
